摘要
由于动画设计中常因人物面部表情生硬不自然,导致观众期待值得不到满足,提出三维人物微表情制作对动画设计的影响分析.提取真实人脸特征,利用面部动作编码系统,缩小邻域间的深度距离,将三维面部表情归一化,结合正面与侧面的三维人物表情特征点,提取表情序列中的三维帧,计算面部特征点影响区域内的非特征点的运动因子,获取面部动画参数值,利用三维比例因子,控制面部变形,定位三维网格点纹理坐标,实现三维人物微表情制作对动画设计的影响分析.实验结果表明,三维人物微表情的应用能够有效增加动画设计的真实性,令人物表情更生动,使人物情绪表达更加丰富.
Because of the stiff aper puts forward the analysis of the influence of 3D micro expression on animation design.Extract the real face features,use the facial motion coding system,reduce the depth distance between neighboring areas,normalize the three-dimensional facial expression,combine the three-dimensional facial expression feature points of the front and side,extract the three-dimensional frame in the expression sequence,calculate the motion factor of the non feature points in the influence area of the facial feature points,obtain the facial animation parameter value,use the three-dimensional scale factor to control Face deformation,positioning the texture coordinates of 3D mesh points,and realizing the analysis of the influence of 3D micro expression production on animation design.The experimental results show that the application of three-dimensional character micro expression can effectively increase the authenticity of animation design,make the character expression more vivid,and make the character expression more rich.
